The Central Valley Regional Water Quality Control Board Thursday fined Teng Vang $83,187 and imposed a $150,000 fine on Kongkeo Khamvongsa and Alexandra Kensavath for failing to clean up cannabis grow sites on property they owned in Shasta County west of Ono.

The actions come nearly two years after the board issued a cleanup and abatement order to Vang and nearly three years after an order was issued to Khamvongsa and Kensavath.

At a Feb. 8 hearing, the board determined Vang, of Sacramento, Khamvongsa, from Wisconsin, and Kensavath of Fresno, failed to restore and monitor their property after board inspectors found evidence of water quality problems related to the development of the land for cannabis cultivation, including the grading and construction of stream crossings and access roads and construction of an earthen dam.

Sediment discharges from Vang’s activities either impacted or threatened to impact tributaries to Ducket Creek and North Fork Cottonwood Creek, both of which support salmon habitat. Vang built an unpermitted surface water diversion to provide irrigation for the cannabis grow.

The activities of Khamvongsa and Kensavath resulted in the discharge and potential discharge of waste to several streams on the property that are tributary to Fidler Creek and North Fork Cottonwood Creek. Both creeks provide salmon habitat near Ono.

The board fines do not relieve the violators and the new property owners of the obligation to clean up the properties.
